Intersection Elevation

[Sword of Damocles]

I am not having performance issues playing the game, however, It seems that it is not possible to change the elevations of intersections, only roads. So if you build a 15m elevation highway, it's not possible to put a highway intersection on it.

Seems like a pretty significant oversight. At least for someone who tries to build a stacked highway.

Haven't tried highways yet but you can put intersections at elevations. Highways are meant to be 1 way with ramps on and off so you shouldn't be putting intersections in them regardless. And I have had no issues in putting an off or on ramp on an elevated highway.
